Hi..thank you for allowing me to join your forum..im new to the pellet stove world and i recently perchased a brand new stove.. about once or twice a day the stove will just shut down.. i can relight it and it may go for 3 hours or more then stops.. when it does stop the blower runs till it cools down then i can relight it... im thinking the air flow adjustment but dont know where the air flow adjustment is locate... when the fire is burning the burning pellets seem to be bouncing around wich makes me think the air flow... any help would be much appreciatted ... P.S the first 2-3 weeks it ran fine and never shut dowb but now were getting temps of minus -20 C ..thank you for any and all suggestions... Bert
